The authentication printing technique of the invention obtains attachment information regarding attachment of a preset device, such as a hard disk drive, to a printing apparatus. In response to a request for a printing operation with the printing apparatus, the authentication printing technique refers to the obtained attachment information and restricts an authentication printing process according to the attachment information of the preset device. The authentication printing process externally receives print data and prints the received print data on completion of a preset authentication operation. This arrangement effectively reduces the potential for leakage of information from the device attached to the printing apparatus.

A host terminal transmits print request information including an IP address to a network printer and provides the network printer with print data in storage in response to an acquisition request. When the print request information is received, the network printer saves the received print request information in storage. When authentication information is received together with a print request, the network printer judges eligibility for using print data on the basis of the authentication information received. When it is judged that a user is eligible to use the print data, the network printer acquires the print data form the host terminal and performs printing. When print request information is not present in the storage, the network printer acquires print request information from other network printers.
